My 422 smallblock build

Update
So after mocking up the rocker arms on the W2 heads it was obvious that some massaging was going to be necessary. I contacted Mike @ B3 Racing Engines about taking on the daunting task of correcting this hodgepodge of mismatched parts and getting things “right”. I had worked with Mike on a previous project and knew he was well qualified for the job.
After initial inspection, it was determined that since these heads were actually two different versions of W2s, they would each require different adjustments to get the geometry corrected. These heads were both born as Econos, with the cast pedestals, but I had the pedestals machined off in order to run blocks as the race heads do. Well it turns out that one head was originally a long valve version and one was not. Therefore they were machined differently at the factory and now requied different blocks between the two heads. One head requires the on-center blocks and the other requires the offset-drilled blocks. After Mike figured that out, I ordered the appropriate blocks from Angelucci Mfg (fantastic company!) and Mike commenced to correcting a previously done poor valve job and bowl clean up.
After getting the heads back from B3, I installed them on the short block and proceeded to measure for pushrods. I used a TrickFlow adjustable length checker and set the rocker adjusters to approximately 1-2 threads showing, set lash and got my length. I sent the adjustable pushrod off to Smith Brothers to have a set made up.

Looks great! Mike is a heck of a guy as well. Can't wait to see this puppy in action.
